Conventional expanded polypropylene (EPP) pads used for cushioning assemblies are difficult to cool within seat assemblies. Adding cooling holes for venting in an EPP pad can lead to errors in these pad assemblies. These errors typically result from point loading or improper loading which results in high tensile stresses occurring at the bottom of an EPP pad or pad assembly. As a result, an improved design that can better handle point loading or misalignment can prove beneficial.

With reference to the embodiment shown in FIG 1-10 is generally illustrated, the reference numeral 10 In general, a seat cushion assembly containing a first foam pad 12 includes, at least one air cooling column 14 defined thereby arranged. A pad 16 is over the first foam cushion 12 and the at least one air cooling column 14 arranged. A second foam cushion 18 is under the first foam cushion 12 arranged. The second foam cushion 18 and the first foam cushion 12 define a flow channel 20 in fluid communication with the at least one air cooling column 14 , An air moving device 22 Moves air from an air intake 24 of the flow channel 20 to an air outlet 26 of the flow channel 20 ,

With reference to the 1 and 2 is the seat cushion assembly 10 in a seat 28 a seat assembly 30 It can also be used in any vehicle such as a car, a truck, a van, etc. It is also contemplated that the concept set forth in this disclosure may be in a forward or forward position of the vehicle as well as a rearward position Reverse position of the vehicle can be used. The seat cushion assembly 10 includes a seat base as illustrated 32 on rail slides 34 is positioned to forward and backward movement of the seat cushion assembly 10 relative to the vehicle. The seat 28 is with the seat base 32 and may be moved with respect thereto, as set out in greater detail below. Furthermore includes a seat back 36 the seat assembly 30 a lower loin area 40 and an upper thorax area 42 as well as a headrest 44 , Each of the components of the seat back 36 may be configured for adjustability to support the weight of various sized occupants in the vehicle.

With reference to the 2 and 3 is an aspect of the seat cushion assembly 10 at area II off 1 illustrated. This is concrete first or upper foam cushions 12 illustrated. The upper foam cushion 12 is configured to provide support for the buttocks of an occupant and is also configured to cool the buttocks of the occupant. Two air cooling columns 14 are in range II illustrated. It is understood, however, that any number of air cooling columns through the upper foam pad 12 can be present. As in 3 shown are the air cooling columns 14 at an upper portion thereof, and include a recessed circumference 50 that helps to cool an occupant. A lower section 52 of the first foam pad 12 includes enlarged recesses 54 , which together with the second foam cushion 18 the flow channels 20 define. It is understood that the first foam cushion 12 can take a variety of shapes and constructions and that the illustrated construction is exemplary.

With reference to the 4 and 5 is the second or lower foam pad 18 illustrated. The second foam cushion 18 includes upwardly extending columns 60 that are configured in the recesses 54 of the first foam pad 12 to protrude. The second foam cushion 18 includes an upper portion thereof, the cavities 62 Are defined. The cavities 62 and the columns 60 the first and second foam pad 12 . 18 define together the flow channel 20 , As with the first foam cushion 12 can the second foam cushion 18 assume a variety of shapes and constructions and it is not on the in the 4 and 5 limited construction.

With reference to 6 is the seat cushion assembly 10 from the pad 16 , the first foam cushion 12 and the second foam pad 18 exists, illustrated. The pad 16 generally has a porous construction, allowing fluid or air through the support pad 16 can get. It is understood that air in the pad 16 pulled or can be blown out of this. The air movement device 22 pushes air through the air intake 24 of the flow channel 20 , The air movement device 22 may be a blower, the air from the air intake 24 of the flow channel 20 to the air outlet 26 of the flow channel 20 suppressed. In the illustrated embodiment, the air inlet 24 in a horizontal direction relative to the seat cushion assembly 10 aligned. It is understood, however, that the air intake 24 also in a vertical direction relative to the seat cushion assembly 10 can be aligned. The air movement device 22 pushes air into the air intake 24 of the flow channel 20 until the air is the first vertical air cooling column 14 reached. The air can then move in a turbulent manner, generally in the direction of the arrows 61 , move, causing the pad 16 is cooled and therefore the occupant is cooled. Air enters a first internal transfer section 63 of the flow channel 20 pressed. The first inner transmission section 63 includes a first lateral section 64 , which has a second lateral section 66 through a vertical section 68 combines. The flow of fluid, which may be air, is generally laminar when the fluid passes through the first internal transfer section 63 arrives. However, the flow of fluid is within the first and second air cooling columns 14 generally turbulent. It should be understood that this construction is exemplary and that other constructions may also be used. Air, which is still a bit chilled, but some heat gain from the first air cooling column 14 has received, is then in the second air cooling column 14 passed to the pad 16 and thus the occupant at a location near the second air cooling column 14 to cool. Air also passes along the rear section of the air cooling column 14 and a second inner transfer section 72 pressed, the first side section 74 Includes a second side section 76 through a vertical section 78 combines. The heated air eventually leaves the seat cushion assembly 10 through the air outlet 26 ,

With reference to the 7 and 8th is an example of the upper foam pad 12 illustrated. The upper foam cushion 12 , as in 8th shows a variety of air cooling columns 14 , Additionally includes a bottom page 80 of the upper foam pad 12 the multitude of air cooling columns 14 that have grooves 82 that form a section of the flow channels 20 form, in fluid communication. Each of the grooves 82 is in communication with an airmover hole that houses the air intake 24 Are defined. It is understood that the air movement device 22 Air from the cushion 16 the seat cushion assembly 10 can draw or air to the pad 16 the seat cushion assembly 10 can press.

With reference to the 9 and 10 is the second foam cushion 18 illustrated. The second foam cushion 18 has a similar construction to the first foam pad 12 on, but this air cooling columns are missing 14 that are in communication with the pad 16 stand. However, includes an upper side 90 of the second foam pad 18 a variety of grooves 92 that together with the grooves 82 of the upper foam pad 12 the flow channels 20 form. As with the grooves 82 of the first foam pad 12 stand the grooves 92 of the lower foam pad 18 ultimately in communication with the airmover hole at a rear portion the seat cushion assembly 10 , Attachment features are under the second foam pad 18 arranged and configured to the second foam pad 18 to secure to an underlying seat suspension assembly.
